Native apps for
focused work
We make apps that feel like they came with your Mac. Simple tools that do their job beautifully, so you can focus on yours.
How we build
Native first
Our apps are built for macOS and iOS from the ground up. Every interaction feels like it belongs on the platform.
Design obsessed
The bar is Apple, Braun, B&O. If an interaction doesn't feel inevitable, we haven't finished designing it.
Privacy respecting
Your data stays on your device. Our apps work offline and we have no interest in what you do with them.
Open where possible
The MarkBooks format is CC0. Our specifications are public. Proprietary lock-in is not a business model.
